At the closed end of the cylinder there is a small flanged boss or projection C, while at the end of the cylinder through which the piston-rod passes there is a larger opening D, having the flange E, as shown. These structures are pressed from one piece of metal in one operation by suitable dies.

l/VhatI claim as my invention, and desire to secure by Letters Patent, is

2. The cylinder-casing A, having the inwardly-projecting fiangeB and the outwardlyprojecting flange E, all pressed from one piece of steel, substantially as described.
